What happens here

To effectively break the thick, reinforced concrete of the pool, a large, heavy boulder is introduced. The excavator carefully lifts the boulder and drops it repeatedly onto the pool's concrete surfaces, creating stress fractures and breaking the concrete into manageable pieces. This method is described as a 'secret weapon' for such tough demolitions.

Goal: Create stress fractures in heavily reinforced concrete using a large boulder

Tools and materials

  • Kobelco Excavator Kobelco — Lifting and dropping the boulder

job you know we used to do all the typical things saw cut the pools jackhammer I even bought a giant camera just to remove concrete swimming pools and then I tried a boulder it doesn't look like it does much but it doesn't have to do much all it has to do is create enough of a stress fracture that allows us to get our teeth into the concrete to do the rest I think a boulder is kind of like a part of you've eaten too much steak silent but deadly
